Corrupted Flash - Rebuilding the list of drives

[devanchya]

My flash drive died last night after Years of good service.  The famous bzboot boot bug that I see on some corruption pages.

 

Now my issue is, the drive is good enough to read from... but I don't know how to restore my drive listing.  The screen shot I have is missing a few drives, forgot to update it.

 

I have the syslog from a (few) months and I can see drive0 to drive 19.  which is the parity drive?

figured it out.  Don't start up a disk array with parity installed while testing this.

 

Disk 0 was Parity.  Disk 1 through 19 where Disk 1 through 19, and the cache was the final disk.
